Dear victorlrf,
Welcome to the forum.
In my opinion you'd better off posting that in the help forum, in which you can have more help since in your code you are not using the extension as far as I can tell.

And another gold rule is to embed your code using the HTML or PHP tags, so that it is more readable and you have more chances to get help and fix your problems.

thanks

thanks

does not work?
I guess because to display the mask takes time and if the rendering of the tree start strightaway after treePanel.body.mask("Loading data...") the mask does not show up since the browser freezes before displaying it...
